Designing the perfect membrane for clean separation of gases

Selective removal of detrimental gases, e.g., hydrogen sulfide (H2S) and carbon dioxide (CO2) from natural gas (CH4) could become simpler and highly effective using a new class of oriented mixed-matrix metal-organic framework ...

Tracking the nitric oxide signaling pathway

Both nitric oxide (NO) and hydrogen sulfide (H2S) act as gaseous signaling molecules with similar physiological effects. Many of the critical questions about the interplay between these two gasotransmitters hinge on their ...

Thumb-sized device quickly 'sniffs out' bad breath

No one wants bad breath—not when visiting friends and family, at a job interview, and especially not on a first date. Smelly breath can make things awkward, but it also is a natural warning sign, indicating that serious ...

Sulfur enhances carbon storage in the Black Sea

A study led by Oldenburg researchers finds new explanation for the accumulation of organic compounds in oxygen-depleted marine areas. The effect could negatively feedback on the climate on geological time scales.
